JOSEPH A. GITS, OF CHICAGO, ILLINOIS.

AIR GIRCULATOR- Application filed January 18, 1921. Serial No. 438,233.

T all whom it may concern v Be it known that I, JOSEPH A. Grrs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful improvement in Air Circulators of which the following is a specification.

In ordinary hot air heating plants there is always great difficulty in causing the air to circulate through the furnace and the rooms to be heated with proper rapidity to secure eiiicient use of the number of heat units generated by the furnace. it is also well understood in such devices that when the wind out of doors is blowing in a certain direction with reference to the building being heated, it is always difficult and sometimes impossible to make the hot air travel into and heat the room or rooms on the side of the building against which the wind strikes.

The object of this invention is to provide in general an air circulating mechanism and in particular one applicable to hot air turnaces operating under the conditions described which will insure under all conditions circulation of the heated air.

The invention consists in means capable of carrying out the fore-going objects, which can be made either integral with the heating system, or as a separate assembly readilyapplicable in heating; systems already constructed and for so doing this the device can be comparatively and cheaply constructed that it is satisfactory and efficient in use, is not readily liable to get out of order and if does get out of order can be readily remover.

' for repair. The invention further consists n many features and details of construction.

hereafter more fully set forth in the speciiication and claims.

Referring to the drawings in which like numerals designate the same parts through out the several views:

Figure 1 is a perspective view of orninary hot air furnace showing the device of this invention applied thereto.

Figure 2 is aplan view, partially tion, of the unitary assembly ready for appli cation to a furnace, the left hand half being shown partially in section.

Figure 8 is a perspective face view of I mechanism of Figure 2.

Figure 4: is aface perspective View of the motor mechanism of Figures 2 and 3 removed from the rest of the device.

- circumferential d1 Figure 5 is a perspective view of the parts of Figure 3 which are left after the mechanism of Figure 4: isreinoved.

Furnaces and other air conveying pipes to which the device of this invention may be applied vary greatly in size and one special object of this invention is to nrovidea fan mechanism in combination with a hot air pipe section adjustable in size so that it may be after adjustment applied and used in connec- 5 'tion with any required pipe construction. in

carrying out this last mentioned object, the pipe section shown in the igures 5 and 3 is provided, consisting of two parallel rings 10 and 12 adjustable in circumferential length in the ticular case through the agency of pin and slot or more accurately screw and slot connection l4-16 of ordinary constrziction so arranged that by loosening screws 1% and contracting or ending it and 12 within the h of the slots "'6 and then resetti 14 the circu -Zerences of these i suitably connected. together at prefers l r as shown i 1 pin and connections and rigid able means tending 1 iy secu i as shown overlap; the pin an slot tonnections heretofore iescribed., is cumierential perforate i late 22 attac ed to the members l0 and 12 by any suitable means the drawing, Similarly intendi opposite cross bars 29 around to slot connections 1 1 l?) and in a. lapping the adjacent e 1 of member 26 is an imperiorate cover member the end of this in riding 1; i device te member 26 is ccnce connecting naenio by circumferential p ably le in place,

w. m removable SCfoliS all,

member and cut member 18 or 20, as the case may be. Depending from the under side of this removable plate 30 and extending towards the interior of the adjustable pipe section, just described, are suitable bracket members, which in the particular case here illustrated take the form of rods 34, suitably secured to the plate 30 by any suitable means, as for instance the rivets shown. These rods in the particular case here illustrated, four in number, sustain a platform 36 on which is rigidly secured by any suitable means a conventional form of fan motor 38 driving the fan blades 40. This motor 38 is supplied with an electric current by a cord 42 of conventional construction which, in the particular case here illustrated passes through a resistance 44 to cut down the motor speed suspended below the plate 30 and thence through a suitably insulated passage 46 to the connector plug 48, which in Figure 1 is shown attached to an ordinary electric light fixture 50 in the room in which the conventional hot air furnace 52 is shown installed.

In the installation of Figure 1 the unitary mechanism of this invention, heretofore described is shown installed in connection with the air supply pipe 54 of the furnace, the fan blades 40 belng so ointed that when'electrio current is turned on and the fan is operated air will be sucked downward through pipe 54 and forced into the furnace 52 under sufficient pressure so that it travels out of the various furnace deliver ipes 56 with sufiicient velocity so that it Wll travel to all parts of the building to be heated by the furnace 52 regardless of outside wind and other conditions.

Users of this device find it advantageous to operate the fan in hot weather when there is no fire in the furnace in order that the warm outslde air may be carried into the normally cool basement and furnace equipment and thus reduced in temperature and thereafter delivered to the rooms under good circulatingI velocity.

ommercially it is desirable to, when possible, provide the pipe section and fan equipment of the drawings complete for installat on in connection with the furnace or other ainpipes to be equipped. It is, however, entirely possible to sell the equi ament shown in Flgure 4 as a separate unit and let the installer simply make a hole in his already installed pipe of sufficient size So that the fan mechanism may be inserted through it and the opening closed by member 30.

When the complete equipment is sold it is delivered in the condition shown in Figure 3 and the installer adjusts the pipe section to this particular pipe in which it is to be used by loosening the screws 14 and expandmg or contracting the rings 10 and 12 as necessary and then tightening the screws 14 in conventional manner. When this has been done the pipe section is instaned in the furnace pipe 54 or its equivalent; H16111 ber 48 is connected to an electric fixture, on turning on of the current the fan operates to perform its proper functions. If, for any reason it is desirable to repair' the fan, the operator has only to remove the screws 32, lift ofi the plate 30, with fan mechanism attached thereto, without disturbing the remainder of the pipe section.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In mechanism of the class described, a section of air pipe circumferentially open at one side, a plate detachably closing the open side, a fan motor mechanism carried by the plate, positioned when the plate is in place inside the pipe and means for conducting an electric currentto the motor mech amsm.

' 2. In mechanism of the class described, a pipe section made up of two parallel circumferential rings severed at suitable points in their circumferences, means at said points of severence for adjusting the ultimate circumferential lengths of said rings, means on the rings remote from the adjustment point of the rings for attaching a fan motor carrying plate thereto, a plate and a fan motor detachably secured to the rings at the last mentioned point and imperforate circumferential bands extending from opposite sides of the fan carrying plate around the ring to and over the adjustment points, adjustably overlapping each other at that point, for the purposes set forth.

3. A pipe section made up of a pair of spaced apart rings adjustable as to circumferential length and three plate sections of imperforate material arranged around the outside of said rings, two of said plate sec tions overlapping each other to permit circumferential length. adjustment as the rings are adjusted, the third a detachable plate carrying a fan motor equipment insertable in and removable from the resulting pipe as the last mentioned plate section is inserted in working position or removed.

4. A pipe section for insertion in connection with other pipes, means for adjusting the circumference of said pipe section and means attachable toand removable from the pipe section for inserting or removing, as the case may be, within the pipe section an electric fan equipment carried by said removable member.

5. As an article of manufacture, a plate.

for conveying electric current from one side we of the plate to the'fan and motor on the other side of the plate, for the purposes set forth.

6. A pipe section made up of two parallel circumferential rings spaced apart a substantial distance and imperforate cove-r members extending from twoseparated points on the circumference of said rings around the remainder of the pipe section so as to leave a enerally rectan ular perforation in the pipe, between the ends of said first two cover members and means formed in said rings at a point approximately opposite said last mentioned opening for adjusting the lengths of the rings and consequently the diameter of the pipe.

7. A pipe section made up of two parallel circumferential rings spaced apart a substantial distance and imperforate cover members extending from two separated points on the circumference of said rings around the remainder of the pipe section so as to leave a generally rectangular perforation in the pipe, between the ends of said first two cover members, means formed in said rings at a point approximately opposite said last mentioned opening for adjusting plate insertable over said perforation in 30 such a manner that the motor occupies approximately the center of the pipe and.

means for detachably securing said cover member in place, for the purposes described.

8. A "pipe section made up of two parallel circumferential spaced apart rings, means for adjusting the circumferential lengths of said rings, a comparatively short plate in sertable over said rings, as one part of their circumferences, a fan motor mechanism carried by said plate, occupying approximately the centers of said rings when the plate is in position thereon and covering outside the rings for the remainder of their circumferences not occupied by said plate, for the purposes described. 7
